3 Claims. (01. -9131) This invention relates generally to forms for composition walls, and refers more particularly to improvements in prefabricated forms having means for fashioning a sill part on the composition walls.

For example, when producing composition side walls for subfioors or basements ofrbuildings hav-. ing brick or some other type of veneer, it is custernary to form a sill adjacent the top of the side walls at the outer sides of'the latter for supporting the veneer. In cases where prefabricated forms are used to form the composition walls, it is advantageous to provide some means on. the outer wall form which will produce the required sill on the composition wall.

One of the objects of this invention is to provide a form for producing the sill capable of being readily removably clamped to the inner face of the outer wall form by. fastening means which may be readily manipulated.

The foregoing as well as other objects will be made more apparent as this description proceeds; especially when considered in connection with the accompanying drawing, wherein:

Figure 1 is a sectional view showing a prefabricated form in operative relation with a composite wall;

Figure 2 is a fragmentary elevational view of the inner side of theouter wall form;

Figure 3 is a cross sectional view taken onthe line 33 of Figure 1; 1

Figure 4 is a cross sectional view taken on the line 4-4 of Figure 1;

Figure 5 is a perspective view of a clamp forming a part of the fashioning means for the sill form; and

Figure 6 is a perspective view ofanother part of the fashioning means.

In Figure 1 of the drawing the numeral l0 designates generally a prefabricated composition wall form, and the numeral l l designates a composition wall of the type capable of being produced by the form 10. The wall II has a footing l2 at the bottom thereof andhas a sill I3 formed on the outer side of the wall II adjacent the top of the wall. In accordance with conventional practice the sill l3 extends for-the full length of the wall It and is adapted to support suitable veneer (not shown) on the wall I I.

The prefabricated form [0 comprises an inner wall it and an outer wall I5. The two wall forms are composed of a plurality of sections it, and are respectively supported at their lower ends on a pair of rails I! which are suitably fashioned to form the footing l2 of the wall I l. The sectional wall forms l4 and 15 are held in the spaced lateral relationship by means of vertically spaced fastener elements 18.

7 Each fastener element I 8 comprises a tie bar l9 and a pair of, clips/2|] respectively detachably secured to opposite ends of the tie bar. The tie bars 19 extend through aligned openings formed in thelaterallyspaced wall forms'and are tapered to enable readily withdrawing the same when it is desired to dismantle the prefabricated form; The clips 20 for each fastener element respectively extend through suitable slots formed in opposite endsof the associated tie bar and are positioned to respectively abut the outer surfaces of the wall forms. to prevent relative displacement in a laterally outward direction. In addi tion each clip is formed with a hook 2| adapted to hookcover adja'centparts of the wall forms in the manner shown in Figure 1 of the drawing to hold thewall forms against relative inward movement.

The sill l3 on the composition wall H is fashionedbya form 22 which may be produced in sections having a length suitable for convenient handling, and is" preferably channel-shaped in cross section. Regardless of whether the sill form 22 is formed of one piece or in sections, it extends for the' full length of the wall form [5, and is removably clamped to the innerlface of the wall form I5 adjacentthe top of the latter with the base section 23 spaced laterally inwardly from the inner surface of the wall form I5. When the sill form-22 is clamped in the above position on'the wall form [5, the latter serves as aclosure for the channel to prevent theentrance of composition material during the pouring operation.

' Thesill form22 is removably clamped in place by means of aplurality of fastener elements 25.- Each fastener element 25' comprises a bar 26 adapted-to extend through aligned openings respectively formed inthe base 23 of the form 22 and the wall form [5. The opening 21 in the base of the channel-shaped sill form 22 is vertically elongated, and-the registering opening 28 inthewall-form 15 is enlargedwith the result that the position of the sill form 22 relative to the Wall form l5 may be varied to some extent. A head 29 is secured to the inner end of the bar 26 in a position to abut the adjacent side of the sill form 22, and an annular enlargement 30 is formed on the outer end of the rod 26. The enlargement 30 has a diameter less than the diameter of the opening 28 in the wall form [5 and less than the width of the vertically elongated 3 slot 21 through the base of the sill form 22. The arrangement is such as to permit passage of the enlargement 30 through the slot 21 and opening 28 during assembly.

Each fastener element 25 also includes a clip 3| having an elongated slot 32 therethrough terminating at the lower end in an opening 33 having a diameter sufliciently greater than the diameter of the annular enlargement 30 on the associated rod 26 to enable assembling the clip on the rod. As shown particularly in Figure of the drawing, the clip 3| is formed with camsurfaces 34 at opposite sides of the slot 32, and the upper end of the clip is fashioned with an anvil 35 adapted to be engaged by a hammer. The cam surfaces 34 are inclined laterally outwardly from the lower end of the clip, and are respectively engageable with the inner surface of the annular enlargement 30 at opposite sides of the rod 26. The width of the slot 32 is somewhat greater than the diameter of the rod 26 enabling the clip to be moved in a downward direction relative to the rod 26. As the clip is displaced downwardly relative to the rod 26, the enlargement 30 on the rod is engaged by the cam surfaces 34, anddue to the angle of inclination of the cam surfaces, the latter cooperate with the enlargement 36 tending to displace the rod 26 in an outward direction. Inasmuch as the head 29 at the opposite end of the rod abuts the inner side of the sill form in the manner shown in Figure 1 of the drawing, it follows that the sill form is effectively clamped against the wall form l5 by the head 29 in response to downward movement of the clip 3| relative to the rod 26. The arrangement is also such that the sill form 22 may be readily removed b merely striking the lower ends of the clips 3| with a hammer or other tool to move the clips upwardly relative to their respective rods 26. .The clips may then be removed from the rods by merely aligning the openings 33 in the lower ends of the clips with the enlargements 36 on the outer ends of the rods 26, in which position the clips are free tobe slipped off of the rods 26. The rods 26 may then be withdrawn and the sill form removed from assembled relation with the wall form [5.
